Etymology: "Warbling" is the present participle and gerund of "warble", so its history is really the history of that verb. The verb's origin is uncertain. It may be onomatopoeic, imitating the trilling sound of birdsong, but the noun is documented earlier and points somewhere more unexpected. In Middle English the noun "werble" referred to a small creature rather than a sound: the mole cricket, a burrowing insect known for its churring call. That noun came into English from a Frankish source, "werbel", which carried the same sense of the mole cricket. The word has cognates in Walloon, the Romance language spoken in parts of Belgium, where "waerbea" shares the same ancestry. Whether the insect was named for its call, or the call was later associated with the insect, is not settled, which is why the insect and the sound may be linked in ways the records no longer show.
